Designed for live touring, the Shure SM39 is a high-performance wireframe headset, providing a secure and comfortable fit for active singers, speakers, and multi-instrumentalists. It comes equipped with a 3-pin LEMO connector, compatible with Shure wireless bodypacks. The SM39 features a unidirectional cardioid polar pattern with excellent off-axis rejection and high gain before feedback, ensuring minimal signal bleed and feedback—even on loud stages or when positioned near floor monitors. Its mic capsule is finely tuned with a tailored frequency response, delivering best-in-class, crisp speech, and vocal reproduction ideal for live performances.
For precise mic placement, the SM39 features an adjustable microphone boom with a slider element, allowing optimal sound isolation and headset stability—even during intense movements. The lightweight, low-profile, all-black frame ensures comfort during extended use, while maintaining a discreet stage presence. Additionally, the SM39 comes with two locking snap-fit windscreens, effectively reducing plosives, breath noise, and wind interference for clean, intelligible sound in both indoor and outdoor environments.
